As a rule of thumb, we suggest only four types of supplements: protein powder, creatine, nitric oxide boosters, and weight gainers. This article will be detailing the best supplements for muscle growth in each category. Protein Powder Whey protein has been scientifically proven to have the highest rate of absorption among all proteins, including soy and egg whites. It’s also incredibly high in leucine, which can increase muscle mass by stimulating the release of hormones that build muscle....

The helmet-mounted radios were originally implemented as a safety device that would allow directors to caution riders regarding accidents, treacherous turns, or objects in the road. But the efficient ability they give coaches to communicate continuously with their riders has made them useful in a wider variety of ways. Some in cycling have argued that reliance on the director and access to such critical data have taken strategy away from the bike and placed it in the car....

In the order, President Trump wrote that the current historic levels of unemployment and economic downturn constitute an emergency. Due to that emergency situation, the Administration argues it’s necessary to speed up development in an effort to revive the economy. “Agencies, including executive departments, should take all appropriate steps to use their lawful emergency authorities and other authorities to respond to the national emergency and to facilitate the Nation’s economic recovery,” the order reads....

Electrophorus electricus was first identified by the Swedish zoologist Carl Linnaeus in 1766, and the shocking fish immediately ensnared the collective imagination. In 1806, famous naturalist Alexander Humboldt allegedly attempted to capture some of “die electrischen Fische” by corralling them with his horses. Two of the horses died. For 250 years, scientists have categorized the electric eel as a singular species, completely alone in its genus. That all changed this week....

ULA’s Atlas V launch vehicle relies on Russian engines to get off the ground. Last year those RD-180 engines were banned by Congress from launches involving military and spy satellites, after Russia invaded Crimea, adding even more tension to the U.S.’s already fraught relationship with the former USSR. Although ULA is working on a replacement for the RD-180, its BE-4 is not likely to be ready for the launchpad until 2019 at the earliest....

Whether you don’t want anybody to know you looked up a potentially embarrassing medical condition, or you’re shopping for a gift for someone else in secret, incognito mode can help. What you may not know is that there are several apps other than your browser that also support this private, tracking-free mode. If you need to temporarily go about your business without leaving any tracks, here’s what you need to do....

Research, though, is beginning to highlight some of the potential danger and independent risk they may pose: For example, e-cigarette use is associated with an increased risk of heart disease and heart attack, according to new research presented at the American College of Cardiology’s 68th Annual Scientific Session. “Safer—you can use that term however you want,” says study author Mohinder Vindhyal, an assistant professor at the University of Kansas School of Medicine Wichita....

Check out this exclusive clip from the episode “More Than Human,” hosted by Paul Giamatti, about cyborgs, prosthetics, and augmented humanity.

For the first time ever, materials scientists recorded individual solid atoms moving through a liquid solution. A team of engineers from the National Graphene Institute at the University of Manchester and the University of Cambridge, both in the UK, used a transmission electron microscope to pull off the delicate feat. The technique lets researchers view and take images of miniscule things in extraordinary detail. Typically, however, the subject has to be immobile and held in a high-pressure vacuum system to allow the electrons to scan properly....

But yesterday at the 2016 Waste Management Phoenix Open in Arizona had an even more unique hole-in-one: it was hit by a robot. The robot named LDRIC (Launch Directional Robot Intelligent Circuitry) after Tiger Woods’s birth name, Eldrick is about the size of a golf cart, has a friendly-yet-jaunty facial expression, and a metal arm that wields a club. The machine was developed by Gene Parente, who runs a company called Golf Laboratories, and it isn’t just for fun....

At their site, they describe themselves as Jetpack Purists, noting: The company claims that the JB-9 offers a 10 minute endurance, a top speed over 10 0mph, and a maximum altitude of over 10,000 feet. The device also supposedly has its heritage from a long line of “jet belts,” first built in the late 1960s and early 1970s. Here’s a rocket belt tested for Popular Science in the 2000s: The team of David Mayman and Nelson Tyler say that between them, they have 70 years of experience in jetpack design....

While the JWST has reached this last crucial stage in the setup process, it still has a number of steps and benchmarks before official data capture begins. The JWST is more than a telescope that collects images—it is also a toolbox of scientific equipment. While JWST recently fully aligned its 18 hexagonal mirror segments—a milestone that allows the space telescope to take clearer, sharper pictures of deep space—many of its instruments are still being fine tuned, says Klaus Pontoppidan, project scientist for JWST at the Space Telescope Science Institute....

A few years ago, I was having coffee with an environmental chemist. I happened to mention an ancient method for determining a whale’s age: More than a century ago, whalers learned to examine the creatures’ earwax, which builds up over the years and congeals into a sticky plug. If you extract it from a deceased ani­mal and cut the cylinder in half lengthwise, you’ll see light and dark rings. Researchers think the light bands could be from a buildup of lipids during summer feasting, while the dark ones come from winter fasting....

MOSQUITO FEEDER When it comes to killing people, nothing outdoes the mosquito. In 2020 these disease-wielding insects took out an estimated 627,000 of us with malaria alone, outpacing the rate at which humans kill each other. Entomologists hope to lower that body count by curbing the bugs’ ability to transmit deadly pathogens, but that scholarship requires blood to keep a brood alive. While some labs wean the insects onto convenient diets like rodents, they’re always keener to feed on their natural supply—human hemoglobin, straight from the source....

“We just wanted to wish you a very warm and happy Thanksgiving,” Lindgren said in the video. “We are incredibly thankful for the opportunity to be up here on the International Space Station, working and living in this amazing orbiting laboratory — a physical manifestation of what is possible when great countries work together with communication, cooperation, and collaboration towards peaceful means, to perform research that benefits humanity back on the Earth....

“Our relationship to gravity is a little bit like a fish’s relationship to water,” says Brennan Spiegel, a gastroenterologist at Cedars-Sinai Medical Center in Los Angeles and author of the new paper. “The fish evolved to have a body that survives and thrives in water, even if it may not know it’s in water to begin with.” Similarly, Spiegel explains that while we aren’t always conscious of gravity, it’s a constant influence on our lives....

A book I read in high school by Isaac Asimov opened my eyes to the big bang’s afterglow. It said that researchers had discovered this light that could have come from the explosion. My jaw dropped. In graduate school, I joined a team mapping the stuff with a satellite. Later on, I led a similar mission. Normal photographs capture light that bounces off the subject a fraction of a second before reaching the lens....

Anthropologists theorize that the first boomerangs were heavy projectile objects thrown by hunters to bludgeon a target with speed and accuracy. They were most likely made out of flattened sticks or animal tusks, and weren’t intended to return to their thrower—that is, until someone unknowingly carved the weapon into just the right shape needed for it to spin. A happy accident, huh? Darren Tan is a PhD student in physics at Oxford University....

Some records are a little trickier to define than others, though. Take Death Valley in California as an example. This is the hottest, driest, and lowest national park in the US and is no stranger to intense heat. High temperature averages are 100 degrees Fahrenheit and above for at least a third of the year, and just last week produced the highest daily average temperature observed on the planet at 118....
